To all whom it may concern.-

Be it known that I, ROBERT BURNET, a citizen of the United States, and aresident of East Orange, Essex county, and State of New Jersey, haveinvented new and useful Improvements in Bookbinding Machinery, of whichthe following description, taken in connection with the drawingsherewith accompanying, is a specification.

My invention relates to that class of machinery adapted for bindingbooksthat is, securing the sections forming the filling of the book tothe back of the cover by means of staples; and the invention consists,first, in the means for feeding and driving the staples; second, in themeans for operatingor feeding the table upon which the book to bebound-is secured, and in the means for adjusting the movement or feed ofthe said table, and, third, in the construction of detail parts used incombination with and forming a part of the machine as a whole, in amanner as will hereinafterbe described in detail, and pointed out in theclaims.

The object of my invention is to provide a machine of few parts, ofcheap and simple construction, and provided with the proper means forall necessary adjustments, that will perform the desired function in thequickest, easiest, and best manner. Hence my invention.

Referring to the drawings, Figure 1 represents a front view of myimproved machine; Fig. 2, a side view showing the book secured thereonin proper position to be operated upon; Fig. 3, a sectional view throughline a; m of Fig. 1; Fig. 4, a plan view with the staple feeding anddriving mechanism and the booksupporting table removed; Fig. 5, a sideview of one of the staple supporting and feeding devices detached fromthe machine; Fig. 6,a plan view of the same, and Fig. 7 a cross-seetionthrough linezz: 0c of Fig. 5; Fig. 8, a front view of one of thestaple-driving devices; 45 Fig. 9, a top view of the same, and Fig. 10 asectional view through line a; x of Fig. 8. Fig. 11 is a diagram ofportion of the back of a book with sundry leaves secured therein in themanner practiced by my machine, the

50 view being taken in section through one of the fastening-staples.

In the drawings, A represents the main supporting frame or stand.

B is a hinged or movable frame for the support of the staple feeding anddriving mech- 55. anisin supported above the main frame A and pivotallyconnected or hinged at its rear end with the back of the frame A or apart thereof at a and at its forward end supports the said staplefeeding and driving mechan- 6o ism, which consists of a supporting-plate0, (see Fig. 10,) by which the several operating parts forming the saidstaple feeding and driving mechanism are supported. The plate 0 isprovided with a flange or projection c on its rear side adapted fordovetail connection with the forward end of the frame B, as more clearlyshown in Fig. 3. A section 0 of saidflange or projection c is detachableand adjustably held in position or connection with the plate a by meansof a set-screw 0 in order to allow the said section 0 to be detached ordisconnected from the plate 0 and allow the latter, with the severalparts supported thereby, to be drawn forward and from its connectionwith the frame B in a manner as will be readily understood bythoseskilledin the art and for the purpose of adjusting the position of saiddevices on the frame B or for any other desired object.

0 represents a guid eplate adj ustably supported at a point below theplateo and in line therewith on the end of two rods or plungers 0 0supported and adapted to slide in holes in the supporting-plate c, andis provided with a vertical centrally-arranged groove or guideway c inits rear side, adapted to receive the staples f from a feed-rod c andguide the same in a manner as will hereinafterbe set forth. The saidfeed-rod 0 (shown in detail in Figs. 5, 6, and 7) is secured at one endof the rear side of the guide-plate c with its upper edge, on which thestaples are placed and fed from, central with and adjacent to the saidguideway c in the plate 0 5 and extends from the latter at an upwardinclination, in order that the staples may slide when released by theirfeeding device into the guideway c, in which place they are adjustablyheld until engaged by the stapledriver 0 by a spring a", which issecured on the end of the feed-rod c and at its free end projects acrossthe said guideway c to yieldingly support the staple until engaged bythe staple-driver. The upper edge or section of the feed-rod, which isslightly reduced in size in the instance shown for the reception of thestaples, is provided with a detachable box-like cover a which is adaptedto be slid thereon and be retained in position by groove and counterpartconnection, as clearly shown in Fig. 7, a sufficient space being leftbetween the feed-rod and the said cover for the ready admission andpassage of the staples, the object of the cover being to prevent thestaples from being displaced from their position on the feed-rod whenthe machine is in operation. The staples are adapted to be placed inquantities upon the said feed-rod at its upper free end, and be fedtherefrom one at a time into the guideway c by means of a feeding deviceconsisting of a supporting rod or frame 0 pivotally secured to the saidfeed-rod at c and provided at its front end with an arm or shaft oextending at right angles thereto and over the feed-rod for the supportof a feeding-roll 0 which latter is adapted to be held in engagementwith the upper edge of the feed-rod through an opening in the cover 0 asmore clearly shown in Fig. 5, by means of a spring 0 which is secured tothe feedrod and engages with and exerts an upward pressure on thepivoted supporting rod or frame 0', and thereby holds the feeding-rollsupported at the opposite end of the latter in engagement with thefeed-rod and prevents the staples from sliding therefrom into theguideway 0", except as fed by said feedingroll. The space between theteeth orprojections on the said feeding-roll is of sufficient width forthe admission of the top of a single staple, in order that the roll,when moved or rotated the distance of a single tooth or projection, mayrelease one of the staples and allow it to slide down into the guideway0 A frame carrying a pawl e for engagement with the feeding-r0110, ishinged on the said arm or shaft o and is adapted to be engaged at itsouter end by the forward end of the frame B, (when the latter islowered,) thereby drawing the end of the pawl back into engagement withthe next preceding tooth orprojection 011 the feeding-roll. When theframe B is again raised from contact with the frame 0, the latter israised or moved back to its normal position by means of a spring 0 whichexerts an upward pressure on the same, and the pawl e is caused to moveor rotate the feeding-roll sufficiently to release another staple. Asthe feeding-roll is moved or rotated by the pawl 0 it is retained orheld by a spring pawl or catch 0 which latter is secured on thesupporting rod or frame c. The several engaging or contacting ends orparts of the supporting rod or frame 0 and hinged frame 0 are providedwith adjustingscrews, as more clearly shown in Figs. 5 and 6, adapted toadjust and allow for any undue wear of the several engaging parts.

D represents the table upon which the book to be bound is adapted to besecured, and is supported and adapted to slide or operate in suitablebearings or ways on the frame A. The said table is provided on its underside with a series of teeth or projections (1, adapted to be engagedthrough an opening in the top of the stand A, as shown in Fig. 3, byapawl d, which is pivotally supported on the upper end of a pivotedvertically-arranged rod or lever (P, which latter at its lower end isbifurcated and embraces a cam or eccentric 01 located on a rocking shaft(1 The latter is operated in the instance illustrated in one directionby a foot-lever (I through the medium of a segment or arm d having arigid connection with the shaft (1 and a connecting-rod 01 and in theopposite direction is operated by counterbalance-weights d d A secondstationary pawl or catch d is pivotally supported at one side of andadjacent to the said operating-pawl d, (see Fig. 4,) and is adapted toengage with the said teeth or projections on the under side of the tableD, in order to prevent backward movement of the latter after being movedforward by operating-pawl d. The said pawls d and d are both pivotallysupported a little forward of their center, in order that their engagingends or points may be held in a raised or elevated position forengagement with the teeth or projections d on the table D by the weightof their rear ends. When it is desired to move the table Dback to itsnormal startingpoint after being fed forward by the operating-pawl d,the rear ends of said pawls are elevated to lower their forward engagingpoints from engagement with the teeth or projections (l by a cam oreccentric d (more clearly shown in Fig. 3,) located beneath said rearends of the pawls on a rod or shaft d, which is supported in suitablebearings beneath the table D. The rod or shaft cl projects at one endbeyond the frame A, and is provided with a suitable knob or handle, bywhich the operator may operate said shaft and the cam or eccentricthereon, as will be readily understood.

E represents a device for adjusting the feed or forward movement of thetable D by its operating-pawl d, and it consists, as more clearly shownin Fig. 4, of a plate pivotally supported on the frame or stand Aadjacent to the opening therein through which the pawls d and (1 projectand provided with an arm or extension 6, forming an apron, whichprojects over the said operating-pawl d with its forward end adjacent tothe engaging end or point of said pawl. The front edge of the apron e isadapted to be adjusted in its relative position to the engaging end orpoint of the pawl cl, in order that the said pawl may engage with theteeth or projections (Z on the table D sooner or later by with thepawl-carrying frame 0 shifting or adjusting an arm or extension 6thereof. The latter is adjusted and secured in its adjusted position bya set screw or pin 6 the stand or frame A being provided with a seriesof openings (L for the reception of set screw or pin 6 It will bereadily understood that apron e, projecting over the pawl d, asdescribed, will prevent the engaging end or point of the latter fromengaging the teeth or projections d on the table D until said end orpoint has passed beyond its edge, and by moving or adjusting itsposition the end of the operating-pawl will be released sooner or laterto engage the teeth or projections 01 and thereby adjust the feed of thetable, as will be readily understood by those skilled in the art.

The operation of my improved machine, in brief, is as follows: Theboolccover and the sections to be secured thereto are clamped in a fixedposition on thetable D by suitable clamping devices H H, and theadjusting device E is regulated to adjust the movement or feed of thetable D, according to the amount of space desired between each section.The foot-lever d is then depressed, thereby lowering the forward end ofthe hinged frame B (through the medium of the connecting-rods d and Gand the arm or segment d) and causing the end or the plate 0 to engageor contactwith the book-section I and the staple-driver c at thecontinued downward movementof its supporting-frame to engage the stapleretained in the guidewayc by the retainingspring 0 and push it past thelatter and drive its ends through the sectionand cover and clinch thesame, as will be readily un derstood by those skilled in the art. At thecontinued downward movement of the frame B to operate the staple-driverafter the plate 0 is stationary by reason of its contact with the bookthe forward end I) of said frame B engages and depresses the forward endof the hinged frame 0 and causes the end of the pawl 0, carried thereby,to withdraw into engagement with the next preceding tooth or projectionon the feeding roll or device 0 and as the foot-lever d is released bythe foot of the operator the forward end of the frame 13 and the devicessupported thereby are elevated by means of the counterbalance-weights dand the frame B is raised from contact The latter is then moved orelevated to its normal position by its operating-spring and causes itspawl 0 to move or operate the feeding-roll c to release a staple, whichlatter slides into its receiving-guideway 0 in position to be operatedon by the staple-driver 0 at the next depression of the latter. Thebook-supportd and. move the pawl 01, supported thereby, back intoengagement with the next preceding tooth or projection on the under sideof the tableD, and as the'said hinged frame 13 is elevated bythecounterbalance-weight d the cam or eccentric d is operated in theopposite direction and causes the said operatingpawl d, through themedium of its supporting and operating lever, to move or feed the tableD forward and bring the book secured thereon in its proper relativeposition tothe staple-driver to have the next succeeding section securedto the cover. In order to allow the table D to be moved back to itsnormal starting-point after the book secured thereon has been bound, theengaging ends of the pawls d and d are lowered from engagement with theteeth or projections cl on the under rangement of the several partsforming the, machine as set forth, as it is obvious that various changesmight be madein the construction and arrangement of such parts withoutdeparting from the spirit of my invention.

It will also be understood that the number of the staple feeding anddriving devices used in connection with the machine maybe varied inaccordance with the number of staples desired to be used in securingeach section to the cover. trated in Fig. 1, four of such feeding anddriving devices are shown in position on the machine.
